To ALL WHOM IT MAY coNCERn:

Be it known that IMoR'.rIM'nR 'B rnnsrm.' Mints, of De Witt, Clinton county, and'Statc of Iowa, have' invented e. new und useful Sewing-Horse, lculled Millssuiproved Sewing-Horse;4v and I do hereby declare that' 'the following is a' full, clear, and exact-description of the ccnstructionend peration of the same, reference being had to the annexed drawings,'making :t port ufthis specification, inwhich- 'i l A Figure 1 is n perspective view end` Figures 2, 3, 4, and 5, Vtrainsirer's'e sections. l

In iig. 1, K-represeuts the-seat, to which the jaws A and B nre fixed, A being madeV to work on a binge nt its lower end, and B,stationnry At the'topend ofthe jaw B, and on the inside, is a. feeding-slide, :is seen in A or H, iig. 3. This slide is made withV snwlike teetb,for catching the leather and drawing Ait forward. `It is made to play by the pressing up anddown ofthe rod I, iig. 1, or 'B,'g. 5, said rod being attached nt its top end to the crank C c, iig. 3, which'works on n. bolt or `pin,1 F, g.13, as n fulc'rnm'. 'lbelower end of the ro'd B, Eg. 5, runs through the seat K, ig. 1., und.the-spring-bar a, iig. 5, (whichis bolted to the under 'surface'of. the vseo.t,) and has a thumbnut on both s desV of said' springtbar, to Vadmit of the rod being either lengthened or shortened, and at the same time xed.. f Y

In order .to raiseor lower, the rod B., iig. 5, we have nother rod, H, tig. 1, or C, tig. 5, with n. roller at the top, under which the strop or pulley n, iig. 1, moves. This pulley also runs through both jaws, and over rollers, ns'seen in figs. 2and 3, C und Eone end being tittache'd to the lever E, f'g. 1, rst running through the spiral spring C, iig. 1.A The other :end passes through the 'seat K,- n theoutside of the jaw A, iig'. 1, und` is attnohedto the treadle a, 16g. 4, et C, Aso that by pressingwith-the foot on the treadle it draws on the pulley, which both pulls in the lever E, iig. 1, causing the awl to pierce the. article which is placed between the jws, nnd'also straightening them between the jaws, lit lifts on the rod H, fig. 1, or C, g. 5, cusing the spring-bnr a, fig. 5, to rise, which, upon the letting up ofthe foot, returns to its place. l

The spiral spring G, iig. 1, being compressed at the time the awl is piercing the leather, upon the lifting of the foot throws the lever E, iig. 1, out again. The work is niade to n iove toward the operator by the feedingslide A, iig. 3, or I, iig. 3-aconcave feeder use d instead of the at one for round traces, &c.nnd upon its return is held by the stationary ratchet B, g. 2. 'The length of ,stitch-is regulated by raising or lowering the thumb` nut at the lower end of the rod, C, iig. 5.

G,'g. 5, is one of the guides for the leather to run on, and can be raised or lowered 'as required by lcosening thethumb-nut, ns seen in D, g.` 3. There is also o. guide on. the opposite side of theja'ws, which is worked the same.

This machine is for punching the holes for the needles which are used by the operator.I

D, iig. 1, is a guide for the lever E, iig. 1, to slide in.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Pnten't, i5

l. The feeding-slide, and the manner iii-which it is worked.

2. The mode and operation of punching the holes.' v
